  • Description: Disordered heap and unreasonable disposition of livestock manure in Erhai Lake Basin was the main pollution resource to Erhai. There exist problems in middle temperature biogas engineering, such as low gas production, unstable and easy to crusting. In order to control the farming wastes' pollution and select the suitable middle temperature biogas engineering operation parameters for the anaerobic fermentation process in Erhai Lake basin, taking the dairy manure as sampling, this study investigated the effects of temperature, substrate concentration and inorganic stimulating factors on the middle temperature anaerobic fermentation efficiency. What's more, the amount of trace elements was optimized with response surface method in the paper. The experimental conditions were 600 mL total volume of fermentation broth, 8% total solids content with a 30 days fermentation period. The results showed a fine effect between real values and predicted values of central composite experimental used quadratic polynomial fitti
